Well since I got no response I suppose that I might have not expressed myself properly.<div><div><br></div><div>The problem is that I don't know howto tell nginx that there is no information and to go on with the next request in the output buffer chain. I looked at other modules and google around but couldn't find any information that I could use.</div>

<div>This happens when I only have a very small chain that won't get processed (I put in the ctx to process the next time), so the call to ngx_http_next_body_filter(r, in) basically don't has any output to process.</div>
